Doppler Fetal Heart Rate (FHR) Detector model BF515 applies the ultrasonic Dopple principle
to detect the fetal heart beat. The units are compact, lightweight, easy to operate with stable
performance and high dependability.
² Delicate, handle, probe integrated with main unit, pulse working mode, and built-in loudspeaker
² Water-proof design, work under the water, and specially designed for water delivery.
² Bluetooth function, FHR data can be transfered to PC with WIFI. There is the lock function for fetal heart rate.
² Three working modes: instantaneous, average and manual count mode.
² Blue backlight LCD displays fetal heart rate and other information such as low power indicator and alarm indicator for abnormal FHR etc.
² Excellent power management function: the backlight will power off after 10 seconds without signal input.
² Adopt DSP technology which is the same with fetal monitor, to make sure accurate and stable fetal heart rate detection.
